Cercis plant named &#39;NCCC1&#39;

ABSTRACT

‘NCCC1’ is a new cultivar of eastern redbud tree with unique, multi-colored foliage that includes a range and combination of colors including green, white, purple, and pink on emerging and young foliage.

LATIN NAME OF THE GENUS AND SPECIES

The Latin name of the novel plant variety disclosed herein is Cercis canadensis.

VARIETY DENOMINATION

The inventive variety of the Cercis canadensis disclosed herein has been given the varietal denomination ‘NCCC1’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct hybrid cultivar of Cercis canadensis herein referred to by the cultivar name ‘NCCC1’. This new redbud was developed through a breeding program at North Carolina State University, Mills River, N.C. ‘NCCC1’ was selected from a population of second generation descendants from hybrids between Cercis canadensis ‘Forest Pansy’ (U.S. Plant Pat. No. 2,556) and Cercis canadensis ‘Silver Cloud’ (non-patented). Plants of the original F₁ hybrids between ‘Forest Pansy’ and ‘Silver Cloud’ were planted in Mills River, N.C., and isolated from other Cercis. Open pollenated seeds were collected from these trees in 2004 and germinated in the spring of 2005. Nineteen seedlings were selected that expressed purple and/or variegated foliage traits and were also planted in Mills River, N.C. ‘NCCC1’, originally designated as H2005-055-003, was selected primarily for its attractive multi-colored foliage in spring and early summer. The first asexual propagation of ‘NCCC1’ was carried out in 2009 by budding at a nursery in Belvidere, Tenn. ‘NCCC1’ has been found to retain its distinctive characteristics, through repeated asexual propagation, over a 9-year period.

SUMMARY OF THE INVENTION

The following are the unique and distinguishing characteristics of this new cultivar when grown under standard horticultural practices at North Carolina State University, Mills River, N.C.: emerging and young leaves express a range and combination of colors including green, white, purple, and pink.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of the botanical characteristics of the new and distinct variety of the redbud tree known by the denomination ‘NCCC1’. The detailed description was taken on an eight-year-old field-grown tree in Mills River, N.C. in April-October of 2013. All colors cited herein refer to The Royal Horticultural Society Colour Chart (The Royal Horticultural Society (R.H.S.), London, 2001 Edition). Where specific dimensions, sizes, colors, and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable.
